SODA-WATER VALVE.

Specification of Letters Patent.

Patented Jan. 14,1913.

Application filed April 27, 1912. Serial No. 693,587.

To all whom it may concern Be it known that I, CHARLES F. FREESE, acitizen of the United States of America, and resident of Fort Wayne, inthe county of Allen and State of Indiana, have invented certain new anduseful Improvements in Soda-Water Valves, of which the following is aspecification. I v

This invention relates to improvements in soda-water valves for mixturescomposed of syrup and soda-water, and the object of the improvement isto afford a valve for controlling the flow of.soda-water and syrupsimultaneously or separately, and to regulate the quantitative dischargeof syrup.

The object of the invention is accomplished by the constructionillustrated in the accompanying drawings in which:

Figure 1 is a plan view of the device partly broken away; Fig. 2 is anelevation ofthe same partly in vertical section; Fig. 3 is a transversesection of Fig. 4 on the line wa2 thereof. Fig. 4 is a rear elevation ofthe device; Fig. 5 is an elevation showlng a supply tank for syrup and agas tank in connection therewith; and Fig. 6 is an elevation showing thedischarge end of a sodawater supply tank.

Similar numerals of reference indicate corresponding arts throughout theseveral views and re erring now to the same :-1 is a valve-case, havingconnected with its lower end a cylindrical cup 2 in which is arranged aloose piston 3. Within the case is arranged a valve 4 and within thevalve 4 is a secondary valve 5 having an operating stem 6, the valveshavin a common axial center. The valve 5 has a ange 7 in which is made arecess 8, and the valve 4 has in its upper end a screw 9. the head ofwhich extends into the recess and limits the turning movement of thevalve 5 relative to the valve 4 by coming into contact with the flangeat the respective end of the recess. The valve 4 is turned in the casingby the manipulation of the valve 5. The casing has four opposite ports10 and 10 and 11 and 11. Upon one side of the valve 4 is a pocket 12adapted to connect either the ports 10 and 11 or the ports 10 and 11'accordingly as the valve is turned, and upon the opposite side of thevalve is a port 13 adapted to communicate at its upper end with theports 11 and 11 correspondlng ports 15 and 15 in the case.-

The valve 5 has a transverse port 16, and the valve 4 has ports 17 and18 in line therewith and which are adapted to register with the ports 11and 11' when properly turned.

A plate 4 secured to the bottom of the valve 4 acts against the adjacentend of the case and holds the valve in place. Upon one side of the caseis a spout 19 containing discharge pipes 20 and '21, the former havingconnection at its inner end with the port 1. in the case, and the latterpipe having connection with the port 15 through an extension pipe 22.The outer ends of the discharge pipes 20 and 21 extend through a plug 23in the spout, and terminate within a hood 24 secured to the end of thespout. The ports 10 and 10' each have connection with the lower part ofthe-cylindrical cup 2 through a Y pipe 25.

Upon the stem 6 of the valve 5 is a handle 26 by which the valve ismanipulated, and through the bottom of the cylindrical cup extends anadjusting screw 27 by means of which the movement of the piston?) in thecup may be limited more or less accordingly as the screw is turned.

It is the intention that both the syrup and soda-water shall beintroducedinto the valve under pressure from suitable sources of supply,and respective apparatus for supplying same is indicated in Figs. 5 and6. In Fig. 5 28 is a closed tank containing syrup, said tank having adischarge pipe 29 communicating with its lower part, and 30 is a tankcontaining gas under pressure and having connection with the upper partof the tank 28 through a pipe 31. As gas from the tank 30 enters thetank 28, the contents of the latter are expelled through the pipe 29.This pipe has connection with the port 11 in the case 1. In Fig. 6 atank 32 containing the soda-water under pressure is provided with adischarge pipe 33 which has connection with the port 15 in the case 1.

In the operation of the invention, when the valve 4 is in the positionshown in Fig.

2, syrup will enter the upper part of the cylinder 2 through the port 13in the-valve, driving the piston downwardly 1n the cup. The syrup in thecup, beneath the piston, is

expelled, ,by the downward movement of the piston, through the Y pipe 25from whence it passes through the pocket 12 and discharged through thepipe 20. Vhen t e piston strikes t e screw 27 the discharge referred toceases. It is the intention that the port 14 in the valve 4 shallregister with the ports 15 and 15 when the valve is in theflpositionshown m 'F1g. 2 so Y be discharged through the pipe 21, at the' If thevalve 5 be then turned backwardly that soda-water will flow therethroughand same' time the syrup is discharged. through the pipe 20. When thevalvev 4 is turned to a position diametrically opposlte to that justdescribed, the respective posit1ons of the pocket 12 and port 13 willhave been transposed so that syrup will be directed through the pocketand the Y pipe into the lower part of the cup, forcing the piston torise. The contents of the cup, above the piston, are expelled throughthe port 13 and pipe 20. When the valve 4 1s turned so that its ports 17and 18 register respectively with the ports 11 and 11', the port 14 inthe valve will not then register with the corresponding ports in thecase so that soda-water will not then be discharged.

I by disconnecting the source of supply of syrup, the ports, pipes andmeasuring device may be washed-clean of syrup by turning the soda-wateron. The soda-water entering the hood from the pipe 21 is forced backthrough the pipe 20 and from thence into the measuring device, the flowentering either above or below the piston therein accordingly as thevalve is manipulated.
